由 為{幸葍}努か 提交于 2019-11-27 14:53:29
问题 how is it possible to reload data for a cell in my table view? I want to do a request to my Server and the server responses JSON. At the moment I implemented the request and the response handling and I can show the data in my cells. But I want that the server only responses maybe ten datasets. When I scroll to the end of the table view with my ten cells in the app I want to do the next request to my server and the server delivers the next ten datasets and so on. I work with Swift as the

(Rails) Reloading “lib” files without having to restart server…? [duplicate]

由 为君一笑 提交于 2019-11-27 14:29:32
问题 This question already has answers here : How do I make the code in lib/ automatically reload when the file changes? (4 answers) Closed 6 years ago . Is there any way in Rails to have the ENV reload "lib" files without having to restart the server? I'm working with some classes that I have inside a module in "lib". However, in order to see my changes I must restart the server each time. I'm guessing this is the way Rails is intended to work, but it is quite tedious when developing library

How to prevent an iframe from reloading when moving it in the DOM

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-11-27 13:31:20
I have an iframe loaded with some content. I would like to move it inside the DOM without causing a refresh (I like the content inside it, I want to keep it). I'm doing some basic node.appendChild(iframe) to do the job. Is that possible? Thanks in advance for your help. If you're trying to move it visually, you can try modifying the CSS to use absolute positioning or some other adjustments. However, if you're trying to actually pull it out of the DOM and insert it somewhere else, you won't be able to avoid a reload. I don't think so, as the browser is going to re-render/reload the iframe when

How to force a page to reload if all what was changed in url is hash?

由 我的梦境 提交于 2019-11-27 11:58:12
问题 I am trying to reload current page with different url hash, but it doesn't work as expected. (Clarification how I want it to work: Reload the page and then scroll to the new hash.) Approach #1: window.location.hash = "#" + newhash; Only scrolls to this anchor without reloading the page. Approach #2: window.location.hash = "#" + newhash; window.location.reload(true); Kinda works but it first scrolls to the anchor, then reloads the page, then scrolls to the anchor again. Approach #3: window

Changing UITableView's section header/footer title without reloading the whole table view

由 半城伤御伤魂 提交于 2019-11-27 08:15:27
Is there any way to reload the section header/footer of a table view without calling [tableView reloadData]; ? In fact, I want to show the number of cells in a table view's section in its section footer. The table view is editable and I delete or insert rows using – insertRowsAtIndexPaths:withRowAnimation: – deleteRowsAtIndexPaths:withRowAnimation: It seems that these methods do not update the section footer. Strangely, when I call these methods the table view data-source method - (NSString *)tableView:(UITableView *)table titleForFooterInSection:(NSInteger)section is called (twice!) but it

ObjectContext.Refresh()?

由 ぐ巨炮叔叔 提交于 2019-11-27 04:16:23
How to update ALL the dirty entities from the data store, and reset their changed values to the original store value? The method ObjectContext.Refresh requires as a parameter the entities to be refreshed. The following usually works: Context.Refresh(RefreshMode.StoreWins, _ Context.ObjectStateManager.GetObjectStateEntries()) It sometimes causes problems with EntityRelations. look at my comment for further details. You can use this code: public void RefreshAll() { // Get all objects in statemanager with entityKey // (context.Refresh will throw an exception otherwise) var refreshableObjects =

Facebook Javascript SDK window location reload not working on Firefox

由 独自空忆成欢 提交于 2019-11-27 03:40:28
问题 I'm building a website with Facebook Connect and therefore using the Facebook Javascript SDK. Problem: when using Firefox, the page doesn't reload properly once logged in or logged out. FB.Event.subscribe( '{% if current_user %}auth.logout{% else %}auth.login{% endif %}', function(response){ window.location.reload(); }); Obviously, it looks like a known problem (just type "window location reload not working on firefox" and you'll get a lot of results) More precisely, Firefox doesn't seem to

Earlier it was working fine. I have been playing little bit config.
